Embodiment 1

[0045] A composite blow bar for a crusher and a manufacturing method thereof, the composite blow bar for a crusher includes a crusher blow bar matrix, which is characterized in that a hard Alloy; the composite embedding refers to embedding cemented carbide in the dovetail groove of the crusher blow hammer base, and further fixing it by welding reinforcement method.

[0046] The manufacturing method of the composite blow bar for the crusher is as follows: a dovetail-shaped notch is opened on the hammering surface of the crusher blow bar base body, and a dovetail-shaped notch is formed on the cemented carbide according to the dovetail shape on the hammering surface of the crusher blow bar base body. The shape and size of the notch is processed into a dovetail block; then the dovetail block on the cemented carbide is clipped into the dovetail-shaped notch on the hammering surface of the crusher blow bar base; finally, the cemented carbide is fixed on the crusher by welding. The b...

Embodiment 2

[0053] A composite blow bar for a crusher and a manufacturing method thereof, the composite blow bar for a crusher includes a crusher blow bar matrix, which is characterized in that a hard Alloy; the composite embedding refers to embedding cemented carbide in the "T" groove of the crusher blow bar base, and further fixing it by welding reinforcement.

[0054] The manufacturing method of the composite blow bar for a crusher is as follows: a "T"-shaped notch is opened on the hammering surface of the crusher blow bar matrix, and a "T"-shaped notch is formed on the cemented carbide according to the hammering surface of the crusher blow bar matrix. The shape and size of the upper "T"-shaped notch is processed into a "T"-shaped protrusion; In the shaped notch; finally, the cemented carbide is fixed on the hammering surface of the crusher blow bar base by welding.

[0055] The specific processing steps are:

[0056] 1. Make a "T" groove on the hammering surface of the hammer base o...

Embodiment 3

[0061] A composite blow bar for a crusher and a manufacturing method thereof, the composite blow bar for a crusher includes a crusher blow bar matrix, which is characterized in that a hard Alloy; the composite embedding refers to embedding cemented carbide in the dovetail groove of the crusher blow bar base, and further fixing it by bonding and strengthening methods.

[0062] The manufacturing method of the composite blow bar for the crusher is as follows: a dovetail-shaped notch is opened on the hammering surface of the crusher blow bar base body, and a dovetail-shaped notch is formed on the cemented carbide according to the dovetail shape on the hammering surface of the crusher blow bar base body. The shape and size of the notch is processed into a dovetail block; then the dovetail block on the cemented carbide is snapped into the dovetail-shaped notch on the hammering surface of the crusher blow bar base; finally, the cemented carbide is fixed on the crushing surface by bond...

Abstract

The invention provides a composite board hammer for a crusher and a production method of the same. The composite board hammer for the crusher comprises a crusher board hammer base, and is characterized in that: a hard alloy is inserted on a hammering face of the crusher board hammer base in a composite manner, namely, the hard alloy is inserted in a groove of the crusher board hammer base, and is further fixed through an auxiliary reinforcing method. According to the composite board hammer provided by the invention, by adopting a special method, hardness of the hammering face of the original high manganese steel board hammer base for crusher is raised from HRA to HRA88, and therefore abrasive resistance of the board hammer is effectively improved.

Description

technical field [0001] The invention relates to a manufacturing method and a product of mechanical equipment parts, in particular to a manufacturing method of a blow bar for a crusher and a composite blow bar. It is mainly used for the production of the blow bar of the crusher. Background technique [0002] A crusher is a crushing machine that uses impact energy to crush materials. Commonly used crushers include jaw crushers, impact crushers, gyratory crushers, cone crushers, roll crushers, hammer crushers and vertical shaft crushers. Impact crusher and so on. The blow bar is an important part of the crusher for crushing the blow bar. The wear of the blow bar is the main failure mode of the crusher. Generally, the service life of the blow bar is short and the consumption is large. Need to reserve a large number of spare parts to maintain normal production. There are generally two reasons for the short service life of the blow bar due to high production costs: [0003] On...
